基于阻抗分析法的柔性直流馈入容量计算方法
Calculation Method for Flexible DC Infeed Capacity Based on Impedance Analysis
摘要
Abstract
Determining the reasonable limit value of reasonable DC infeed capacity to ensure safe and stable operation of power grid is of great significance.According to the Nyquist criterion,a method is proposed based on impedance analysis to calculate the limit capacity of the grid-connected flexible DC transmission system.It makes the method simple so only the ratio of the grid impedance to the converter impedance is needed rather than learning about the inside of the converter.Through a simulation analysis on an IEEE 3 9-node system,the validity of the proposed method is verified,and the impact on the limit infeed capacity in the DC transmission system is briefly treated.关键词
